Keeping your water filter upright


By Jim Twamley

A water filter is a great idea because it keeps impurities from contaminating your water system. There are many different types and degrees of water filtration available to RVers. I use a whole house single filter with a combo charcoal filter (purchased at Home Depot – with appropriate brass hose adapters). This filter gets the debris and also takes out a few harmful bacteria.

Unfortunately, the filter will not stay in an upright position without help. Solution? I use an old chlorine bucket because it has a sturdy screw-on lid. I cut a hole in the lid for the filter and drilled holes in the bottom of the bucket to allow water to drain. This makes a nice platform for the filter to rest in. It will not blow over (unless you are in a hurricane – in which case water filtration is the least of your worries) and it will rest on any flat surface. It can also be used to store a short length of coiled hose.

I had a construction cone laying around. I cut the top off enough to fit my whole house filter inside. It’s bright orange so no one trips over it & it’s lasted over 30 years.

A very effective way to hold it is – buy an orange traffic cone, (about $15.00) cut the top down to the size of your filter case. (Save the cut off top and use for an exhaust cover when the vehicle is in storage especially if outdoor storage in snow country. PS: add a WD-40 spray can lid to the hole in the center of the cut off top). In the event of a road emergency you will also have the cone to alert other drivers! (Also a visual reminder before leaving a camp site).

I have a five gallon bucket turned upside down with the appropriate hole cut in the top where the filter slides in perfectly. I see NO reason for a filter having to be ‘stand up’, but I just think it looks neater.

The water comes in the inlet, is forced through the filter material and goes out the outlet. I fail to see any need to keep the filter upright.

And why does it have to sit upright? Water can only go in one direction thru the filter no matter the orientation.

Our mh came with a filter mounted after the inlet, I added a sediment filter before the water entrance and use a carbon filter where the factory filter is, the sediment filter catches all the dirt and trash that would normally plug the carbon filter and let’s that filter last up to 3 months. The sediment filters are cheap and I replace it every 30-45 days, it catches everything down to 10 microns. I found the inline blue filters only filter down to 20 microns which means the dirt you can see with your eyes.

I use a milk crate. With the appropriate cut outs at the bottom, the filter is well secured in the upside-down crate. Just slightly higher than the filter, it is out of sight and out of the elements under our Class A when in use. It is also short and compact for storage. Works very well for me.
